I am planning to create map-based online questionnair/survey for my master dissertation on bicyle safety. What I want to do is, asking my potential respondants to mark their answers by adding pins/mark on Online map I create. For example, I ask them a question like, " where did you have a near-miss incident while you are on a bicycle?", then respondant can answer that question by locating pins/mark on where they had nearmiss.
My initial investigaton suggested that I can achieve this with Google map API, ArcGIS online or Crowdmap. I have seen some crowd-sourced maps with a lot of pins located by many people. But I am not sure if I can;
- download all these marked locations in csv/text file with xy coordinate
- make my survey map accessable only for my "group"
Can anybody suggest me what can I use (Google API, crowdmap, ArcGIS online or else) to achieve above 1 and 2 without any or with little programming?
